Magnetic field lines are basically a geometrical representation of a magnetic field
They are continuous because the field (magnetic) is continuous as well
They are curved to make sure they do not intersect (otherwise there would be two directions of magnetic field at same point)
The tangent drawn to the curve of a magnetic field line gives the direction of magnetic force acting

The magnetic field can be defined as:
“A region around/surrounded by a moving electric charge or a magnetic material within which the force of magnetism acts.”
How does Magnetic Field occur?
If you are wondering how Magnetic fields occur. Well, it occurs whenever a charge is in motion. That being said if you apply more charge in the motion the strength of a magnetic field usually increases. Besides, Magnetism and magnetic fields are part of the electromagnetic force which is indeed one of the four prime forces of nature.
